PILE.

Application filed .Tune 20.

rllhis invention relates to piling such as is contemplated by my prior Patent #1,241,813, dated @ctober 2, 1917. In that patent certain provision. wasV made for the utilization of jets of water at the nose ofthe pile and at the 'surface or surfaces of the pile to displace earth in advance of the piling and to lift it to the top of the excavation and at the same time to lubricate the side. of the pile so that it willquickly sink.

In the illustrated embodiment of the invention disclosed in my prior patent of Oc-v tober 2, 1917, a hollow piling was shown with pipes extending longitudinally7 thereof and jet nozzles imbedded therein. While the invention therein disclosed admirablyv serve'd the purposes for which it was intended, I have found that a less expensive pile can be constructed and substantially the same results may bre-obtained by a removable jetting device which may be temporarily attached to the pile for the purpose of hydraulically sinking it into the earth and which may be easily removed after the pile 'F has been sunk to the required depths so the jetting device canbe utilized in connection with another pile.

According `to my present invention, not

only can the pile be made much less expen-Y sively but the necessity ffor leaving the jetting means imbedded in the ground is entirely eliminated, soit is obvious that there will be a considerable saving where a number of piles are sunk.

The novelty of my invention will be apparent 'by reference to. the following description in connection with the accompanying drawings, in which- Fig. 1 is a perspective view of a pile constructed in accordance with my invention, showing the jetting device applied.

Fig. 2 is a vertical longitudinal sectional view through the pile, the jetting device being shown partly in section and partly in elevation.

Fig. 3 is a cross sectional View through the upper portion of the pile and-through the tong receiving socket, and

Fig. 4 is anenlarged detail view of one of the jaws of the tongs.

The pile 1 may be constructed of suitable material such as cement, concrete or the Vlike and it is preferably rectangular in cross section. At the upper'en'd of the pile is a` jaw receiving socket which may consist of a pipe.

2 anchored to the body portion of the pile by anchor wires 3 imbedded in the concrete and having anchoring ends 4 and y5. A cen: ter guide pin 6 is imbedded in the upper endV of the pile. VAt the nose of the pile is a central orifice or opening 7 merging ofi' to the side of the pile at 8 to receive one tube 9 of a jetting device so that water can be forced into the channel consisting of 7 and 8 to displace earth in advance of the pile as will be hereinafter apparent. 1

The jetting device is shown as including a rectangular manifold or tubular ring 10 supplied with water from a tube 11, connected to any suitable source of supply. On three sides of the manifoldare jetting tubes 12, the fourth side supplying the tube 9, all

. of the tubes having upwardly and outwardly Adisposed Jetting nozzles 13 which causes water under pressure to flow along the sides of the pile and since the water is directed upwardly, it will be apparent that the earth which has been displaced by the water issuing from the nozzle or opening 14 in the channel 7 will be elevated by the etted water passing from ythe jets 13, the water also serving t0 lubricate the pile so that it may be allowed tosink by gravity.

rllhe. tubular membersy 12 andV the. member 9 are connectedto the manifold by flexible connections 15, all substantially alike and the tubular members 12 rest upon seats orV projections 16 while the member 9 seats in the open end of the ltube 8. The lower ends of the members 12 are preferably closedv while the lower end of the member 9 is open to communicate with the channel 8 and the tubular portion 7. Means is provided for lowering the pile into position'so that the jetting device may become effective in sinking the pile. The lowering device should be such that it can be detached from the pile after the pile is sunk and it should also be constructed that its withdrawal will be effective in causing the withdrawal of the jetting device, so I have shown the hereinafter described mechanism for accomplishing this result.

The lowering device consists of a tongs comprising two jaws 17 and 18 pivoted to gether at 19 and having co-operating lever, ends 2O and 21 connected by the chains 22 and 23, with a pull cable 24 so that upon Van upward pull of the cable 24 the jaw members 17 and 18 would tend to hold the pins (Si) g es i or lugs 25 and 26 into engagement with the socket member or tube 2. The tongs however are also held in engagement with the tubular member 2 by a retaining bar 27 which is guided in its vertical movement on the pin 6 and which has two slots 28 and 29 through which the upper portions of the jaws 17 and 18 project, there preferably being rollers and 31 so that the bar can ride on the inner curved faces ofthe jaw members 17 and 18 to force the jaws 17 and 18 apart when the bar 27 is raised by the sling 3:2 connected to the cable 33 accessible from the top of the ground.

It will be apparent by reference to Fig. 2 that so long as the retaining or locking bar 27 is in normal position resting upon the top of the pile and held against lateral movement by the pins 6, the. lugs 25 and 26 will hold in the socket 2 but when the bar 27 is raised, to spread the jaws 17 and 18 apart, they must release and since they are connected to the manifold 10, the jetting device will be pulled from the well or excavation made by sinking the pile when the elevating aws or tongs are pulled out. rlhe manifold 10 is connected to the two jaws by the side rods 34 and 85 fastened to the jaw members by the chains 36 and 37, the ends of the rods 311 and being received in the sockets or recesses 3.8 and 39 so that the manifold will be held in its proper position during the jetting, theflefcible connection permitting the movement of the aws to releasing position without disturbing the rods 34 and 35, as obviously these rods could not be moved away from the side of the pile without breaking connection with the niani fold, therefore the engaging ends of the jaws 17 and 18 will have free movement in dependent of the bars or rods 34 and 35.

lt will be apparent however, that just as soon as the pull is exerted by the` tongs, the entire jet-ting frame can be released from the pile and the pile will be submerged orV partially submerged in the earth. Attention is particularly directed to the factthat all of the advantages accruing from the construction shown in my Patent #1,241,813 can be had with the present invention without the necessity of making the pile hollow or imbedding the central water supplying oriiices or channel members therein, therefore the cost of sinking the piles and the cost of the piles themselves will be reduced as compared with the specific arrangement shown in my Patent #1,241,813. In other words, l accomplish all that can be accomplished by my former patent by a much less expensive means and a by no means less important feature is the device for lowering the pile and for raising the jetting devices.

What I claim and desire to secure by Letters-Patent is:

1. ln combination vith a pile having a nozzle at its nose and a transverse socket at its upper end, tongs having jaws for en- Y gag-ing the socket, a jetting frame carried by the tongs and surrounding the pile, the jetting frame having communication with the nozzle, means for supplying water through the frame of the nozzle to remove material in advance of and around the pile and means for releasing the tongs from the pile so that the tongs can be withdrawn and remove the jetting frame.

2. ln combination with a pile structure, a submerging apparatus comprising jetting pipes arranged about the structure, hanger jaws attached to the frame and detachably connected with the pile structure, a lowering cable having Vclosing connection with the jaws, whereby the pile structure and subinerging apparatus are lowered in assembled relation, and a lifting cable having opening connection with the jaws, whereby the jaws are detached from the pile structnre'and the jaws and submerging apparatus removed from the pile structure.

ln testimony whereof I aiiix my signature.. I
